Method Detail

clear

public void clear(java.awt.Graphics g)

Specified by:

clear in interface DragRenderer

getMouseDragEvent

public MouseDragEvent getMouseDragEvent(java.lang.Object source,
                                        java.awt.Point p1,
                                        java.awt.Point p2,
                                        boolean isModified)

This method is called by the DMIA on mouse release. We use this to infer the mouse release and hide the Window. Note this assumes isUpdatingDragSelection is false! TODO: DMIA should call clear so this is more explicit.
